Abstract
Methods and systems for quantitatively determining pack density within a section of a wellbore are disclosed. The method compares acquired pulsed neutron measurements to models of the section having zero pack density and one hundred percent pack density and extrapolates the measured pulsed neutron data between those two extremes to quantitatively determine pack density. The methods and systems allow hydrocarbon saturation and pack density to be determined in a single trip of a pulsed neutron tool.
